UNGOUPLING DEVICE FOR CAR-COUPLINGS.

description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to the construction of uncoupling devices for car couplings, and has for its object the provision of uncoupling devices for operating the coupler lock. said devices connected with each. other and with the lock as not to interfere with the normal movements of the coupler or cause undue-strain upon the coa-cting parts.

To this end my invention generally stated embraces an uncoupling'device for car couplings comprising two members, the first, or main member, adapted to be journaled on a car, the-second. or auxiliary member adapted to loosely engage thelock of a car coupler, oneofsaid members being provided at its end with a vertical'pintle and the' other of said members being provided at its end witlra hub to engagerthe'pintle on the first named member, and .one "of'said members being also provided with a guard to prevent the accidental disengagement of said members when'the device is in service.

- There areother, minor. features of invention, all as will hereinafter more fully appear. a

in the drawings chosen for the purpose of illustrating my invention, the scope whereof" is pointed out in the claim, Figure l is a plan View of uncoupling devices embodying my invention shown as attached to the end of acar and connected with the'locking pin of a vertical plane coupler; Fig. 2 is a view, in front elevation, of the uncoupling devices shown in Fig. 1, and Fig. 3 is a view of the uncoupling devices in side elevation,

1 parts broken away, showing in full line the coupler with the lock in the lower or locked position, and in dotted line the lock in the raised or unlocked position, and the uncoupling devices in the position they assume in raising the lock.

Like symbols refer to like parts wherever they occur. p i I will now proceed to describe my nvention more 'fully so that others-skilled in the Specification of Letters Patent.

art to which it appertains may apply the same.

In the drawings, A indicates the end of a car to which the uncoupling devices are attached. B a coupler. C the knuc (1e. and l) the locking pin thereof, the locking pin having at its upper end an eye or clevis (I through which one end of the auxiliary member of the uncoupling lever passes loosely. 1

As the above noted devices may be of any well known character, and as their connection with the car and mode of operation are well known to those skilled in the art. further description thereof is not here required. i

The numeral 1 indicates the main member V Patented Nov. 21, 1911; I

of the'uncoupling devicesand 2 the auxiliary member. The first these members is journale-d on the car body by brackets 3. or'other'wijse' as; niay be desired, and the second-is so journaled on the first member as to be capable of rotation in a horizontal plane on the journal connection of the members, to-accommodate the longitudinal movementsof the coupler. The member 1 bent at one end as at l to form a crank arm constituting means for rotating said member.

andis bent at theother end at right angles. tot-he arm 1 to form a crank arm or o'lfset member 1 to receive the auxiliary'member 2, which latter member extends to and loosely engages the coupler lock C, when the coupler is not iii servlce. The end of the horizontal crank arm 1 of main member 1 terminates in a vertical pintle 4 for the reception of a'hub on one end of the auxiliary member 2. r

The numeral 2 indicates the auxiliary member of the uncoupling devices. member is provided at one end with a hub 2 by which it pivotally engages the vertical pintle or pin 4; of the main member 1. At

its other end, where it passesthrough the eye on the upper end of the locking pin, the auxiliary member is bent back to form a'hook 2 which insures at all .times the operative connection between the lock and auxiliary member 2 without restricting the necessary independent movement of said parts.

On the auxiliary member 2 and adjacent to the hub 52 thereof is a keeper or guard This member 5 which is adapted to extend under 11 the main member 1 adjacent to pintle 4 thereof, to prevent the accidental discon jecting through the eye nection of the main member 1 and auxiliary member 2 when the uncoupling devices are 1n servlce. In order that the hub of member 2 may be readily slipped on pintle 4 of main member 1, said keeper or guard member 5 is located to one side, or eccentrically disposed, with relation to the hub 2*. This permits the hub to be placed on the vertical pintle or pin 1 when the auxiliary member is alined with crank arm 1", but enables the keeper or guard h1g5 to extend under member 1 and prevent the disengagement of the-parts when the auxiliary member is in its normal, or operative, relation at right angles to said crank arm 1.

The main member 1 having been secured to the car body A by means of the brackets 3, in which said imember 1 is journaled to rotate, said member in its normal position will have the outer crank arm 1* in a vertical pendent position, and the crank arm 1" on its inner endin substantially horizontal position extending forward to carry the auxiliary member 2 into position to engage the lock D of the coupler The auxiliary member 2 which is journaled on the vertical pintle or pin 1 of member 1 will extend in a horizontal hooked end of said auxiliary member prod of the lockmemher to form a hook and eye connection therewith'which will permit of necessary, play between the parts without danger of disengagement when in service. The above noted relation of the parts allows of a sufficient horizontal rotary movement between the same to accommodate all normal movements of the coupler without wear or strain on the coacting parts.

When it is desired to raise the lock D for Copies of this patent may be obtained to uncoupling,

plane to the lock D, the inner.

the pendent arm 1 at the outer end of main member 1 is turned upward and away from the end of the car thus rotating'the main me ber 1 and carrying the horizontal inner arm 1 upward and toward the car. The auxiliary member 2 which is journaled on the pin t at the end of arm 1 of member 1 moves upward and back ward with arm l of member 1, carrying with it the locking pin 1) with which its hooked end 2 engages.

'llaving thus described my'invention, what I claim and desire to secure by Letters Patentis: y

In. an uncoupling device for operating the lock of a car coupler, the combination with a rotatable lever having a plurality of crank arms, one of said crank arms extending forwardly from the car upon which the device.

is mounted and being provided with a pintle forming a vertical angle with. said crank arm, of an auxiliary member'interposed between said rotatable the coupler and adapted to actuate said lock, said auxiliary member being angularly disposed with respect to said forwardly extending crank arm and being being also provided with a guard member, the said hub and guard member being arranged to normally occupy positions on opposite sides of the forwardly extending crank arm. Y a I In testimony whereof I aflix my signature,

in the presence of two subscribing witnesses.
